For a while I have been using the SETI@home screensaver. I do not know much about computer science but my understanding is that the purpose of the program is to create a virtual super computer by breaking up packets of information and then sending them out to all of these computers all over the world which then run them through the program and send back the information. So you end up having the same computing power as a super computer through a large number of home computers. I think this is a fascinating concept but I have 3 questions: 1. How much additional energy does this utilize? I mean is my computer now using the same amount of energy as when it is normally running? 2. Do limits to this system exist? IE what can this kind of system not do that a super computer could? 3. Anyone know of any other programs like this which allow your computer while you are not using it to be searching for knowledge?

Give Me X An IT guy at work told me I shouldn't be shutting down my computer every night because starting up the computer every morning wastes more power than I've saved. I find this hard to believe, but of course I want to use the most energy-efficient option, both at home and at work. So, assuming I've set up screensaver and standby options on my computer, what's the rule of thumb for shutting down? In the equation "X or more hours of non-use = better to shut down and start up later", what does X equal?
